School board unanimously votes to cover up controversial mural

A mural at San Francisco's George Washington High School will be covered per a unanimous vote by the school board, but it's not certain how that will be done. The 86-year-old mural shows slaves picking cotton and settlers stepping over a fallen Native American, which many see as insensitive for students who have to see it every school day. KTVU's Debora Villalon reports.
